On your Application Server (where Outbound is running) go to C:\Program Files (x86)\LANDesk\LANDesk Applications and look at the files ReportSmall.css, ReportMedium.css and ReportLarge.css.

Depending on your report style (Small, Medium or Large) you need to edit one of these CSS files to alter the output of emailed reports. If you want to view these reports in Console in the format you're trying to send in copy those CSS files tpo your local COnsole install directory.

I've had a play with these and got grid lines, font, colours and whole heap of other things working well. I could never figure out how to get an image to send embedded in the report, however I can get it to appear in Console.
